TO ALL WHOM IT MAY CON GERN:

Be it known that I, ROBEM B. Srsnron, ofOxford, in the county of Butler, and State of Ohio, have invented ,a new and improved Reversible Feed Mechanism for Sewing Machines andthat the following descrip- 'tion, taken in connection with the accompanying drawings, hereinafter referred to, forms a full and exact specification of the same, wherein I have set forth the nature and principles of my said improvements, by which my invention may be distingnishedfrom all others of a similar class. together'with such parts as I claim, snails-sire to have secured to me by Letters Patent.

' This invention relates to a newand improved feed mechanism for sewing-machines, so constructedand arranged as to be capable of being reversed and feed thewo'rkeither to the right or left on the cloth-plate,

whereby the removal'of the work from the machine, and the turning of 'it around at the end of each seam or,

row of stitching, is avoided. In the accompanyingsheet of drawings Figure 1 is a frcnt'sectionul view cf my invsnticnytakenin the line a: z, fi 3.

Figure 2, an inverted plan c fi theeloth-plate, with a portion of. the invention applied to it.

Figure 8, a transverse vertical section of the invention, taken in theline y, figi' 1.

Similar letters of reference indicate like parts. a

A representsthe portion of the frame of a sewing machine which supports the cloth-plate B,cnd within this part A of the frame the usual cylinder 0 is placed, having a double cam, D, at one end, for operating the feed-plate Rand the toothed feed-bar F, pivoted within E. These parts are old and well known; and may be seen on the Wheeler and Wilson sewing machine, the periphery of the cam D being the portion which raises the toothed bar F, incontact with the cloth, and the side'c'f Dthe portion which gives the longitudinal movement I to E and F, to feed the cloth along, E and F being thrown back, after -F descends from the cloth, by a spring not shown in the drawing. i i

In addition to the parts above described, and now in common use, I use on the cylinder C two cains G H,

one, G,'adjoining the can. D, and the other, H, being at the opposite end of the cylinder, as shown clearly in fig.

1. The feed-plate E is provided with two pendants a 4', against which 't'he cams D H act'respectively, to give the longitudinal movement to plate E the cam H moving said plate in the direction indicated by arrow 2, and the side of cam D moving it in the direction indicated by arrow 1. The pendant a is fixed or immovable, but

the pendant a is adjustable, it being attached to a slide, 5, on the plate E, which is moved by a screw, 0,. the

latter having a square on its outer end, whieh fits in a revolving socket, I, secured to the under side; of the clothplate B, (see figs. 1 and 2.) By this arrangement the spacc between the two pendants on may be increased or. diminished at pleasure, for the purpose of varying the length of the stitch as'may he required.

J represents an elastic bar, which is pivoted on the upper end of an upright, K, on the base of the. frame.

This bar may be made to rest either onthe cam D or G, as desired, and may be readily shifted from one to the 'other.- This adjustable bar J performs an importantjfeature, as it is the medium through which the toothed bar F is raised by the cams D G. -When, for instance, the bar J rests on the cam D, the toothed bar F will he raised and made to engagewith the cloth, when the plate E is moved in the direction indicated by arrow 1, and when the bar 3' rests on the cam G, the toothed bar 'F willbe raised and made to engage with the cloth when the plate E moves in the direction indicated by arrow 2. Thus, by simply shifting the bar I the feed may be reversed.

To the under side of the cloth-plate-B there is secured a bevelled hook-shaped plate, L, which is near the slot din the cloth-plate, through which the needle and thread pass. This plate L is designed to hold the thread when the cloth is fed or moved in the direction indicated by arrow 2, the bevelled edge 0 allowing the stitch to draw up into the cloth without friction.

,Having thus described my invention, I claim as new, and desire to secure by Letters Patent- 1. The two cams G H, incombination with the cam D and the adjustable elastic bar J, all arranged to operate in connection with the feed-plate E and toothed bur F, substantially as and for the purpose specified- 2. The screw 0, connected with pendant a, in combination with the revolving socket I, as and for the purpose set forth. a v

3. The bevelleclhookshaped plate L, when used in ccnnectioirwith a reversible feed mechanism. as and for the purposespecified.
